Table 9. Read command format/internal status data
Read command bits 1 to 16
These bits form the decoder read command.
Bits 1 to 8 form the actual command, and bits 9 to 16
are dummy data. While command bits 1 to 8 are being
set, data may be output on SDO and can be treated as
indeterminate data and ignored. While bits 9 to 16 are
being set, however, data output on SDO is valid data.
Internal status bit 1 (read command bit 9)
Internal status output data leading bit.
This bit is always 0.
Internal status bit 2 (read command bit 10)
AREA pin condition flag (when reading internal status
data).
When 0, AREA is LOW.
When 1, AREA is HIGH.
Internal status bit 3 (read command bit 11)
Decoder status flag.
When 1, decoder is operating in idle mode.
Internal status bit 4 (read command bit 12)
Decoder status flag.
When 1, decoder is operating in preamble mode.
Internal status bit 5 (read command bit 13)
Decoder status flag.
When 1, decoder is operating in lock mode.
Internal status bit 6 (read command bit 14)
Decoder status flag.
When 1, decoder is operating in write mode.
Internal status bit 7 (read command bit 15)
Decoder status flag.
When 1, decoder is receiving self address or message.
Internal status bit 8 (read command bit 16)
Decoder status flag.
When 1, indicates data write operation to the decoder
internal RAM (BUSY in write mode).
Do not write data when this flag is set to 1.
After each 32-bit data is written, READY confirmation
is not required before writing subsequent data if a space
of 28.4 ms minimum is provided.
